Joining Fortnite Pc with ps4 friends and against ps4 lobbies?

Hey people because I've always gambled with a keyboard and mouse and therefore whenever I've played with my friends who all ne ps4 with controllers have often heard complaints that the opponents are too good and they have an advantage, I'm looking for a solution. I've considered me to get a controller because I used to play ps4 once and then connect the pc. Would we then play zsm against ps4 lobbies as they are used to, or would we still play against pc lobbies?

As before, you would join PC Lobby. Any PS4 player must be, unfortunately.

Nevertheless, have fun!
